public final class ShaderCode
extends Object
```
Convenient shader code class to use and instantiate vertex or fragment programs.
A documented example of how to use this code is available here and here.

Support for GL3ES3.GL_TESS_CONTROL_SHADER and GL3ES3.GL_TESS_EVALUATION_SHADER was added since 2.2.1.

```
    Convenient creation method for instantiating a complete ShaderCode object either from source code using #create(GL2ES2, int, int, Class, String[]), or from a binary code using create(int, int, Class, int, String), whatever is available first.
    The source and binary location names are expected w/o suffixes which are resolved and appended using the given srcSuffixOpt and binSuffixOpt if not null, otherwise getFileSuffix(boolean, int) determines the suffixes.
    
    Additionally, the binary resource is expected within a subfolder of binRoot which reflects the vendor specific binary format, see getBinarySubPath(int). All ShaderUtil.getShaderBinaryFormats(GL) are being iterated using the binary subfolder, the first existing resource is being used.

If false method returns an immutable String instance, which can be passed to GL2ES2.glShaderSource(int, int, String[], IntBuffer) at no additional costs.

                                     throws IOException
```
    Reads shader source located from Uri.absolute Uri sourceLocation.
    
    Parameters:
    
    sourceLocation - Uri location of shader source
    
    mutableStringBuilder - if true method returns a mutable StringBuilder instance which can be edited later on at the costs of a String conversion when passing to GL2ES2.glShaderSource(int, int, String[], IntBuffer). If false method returns an immutable String instance, which can be passed to GL2ES2.glShaderSource(int, int, String[], IntBuffer) at no additional costs.
    
    Throws:
    
    IOException

                                   throws IOException
```
    Reads shader binary located in path, either relative to the context class or absolute as-is.
    Final location lookup is perfomed via ClassLoader.getResource(String) and ClassLoader.getSystemResource(String), see IOUtil#getResource(Class, String).
    
    Parameters:
    
    context - class used to help resolve the source location
    
    path - location of shader binary
    
    Throws:
    
    IOException

```
public static ByteBuffer readShaderBinary(Uri binLocation)
                                   throws IOException
```
    Reads shader binary located from Uri.absolute Uri binLocation.
    
    Parameters:
    
    binLocation - Uri location of shader binary
    
    Throws:
    
    IOException

  - createExtensionDirective
```
public static String createExtensionDirective(String extensionName,
                                              String behavior)
```
    Creates a GLSL extension directive.
    Prefer ENABLE over REQUIRE, since the latter will force a failure if not supported.
    
    Parameters:
    
    extensionName -
    
    behavior - shall be either REQUIRE, ENABLE, DISABLE or WARN
    
    Returns:
    
    the complete extension directive
  - addGLSLVersion
```
public final int addGLSLVersion(GL2ES2 gl)
```
    Add GLSL version at the head of this shader source code.
    Note: The shader source to be edit must be created using a mutable StringBuilder.
    
    Parameters:
    
    gl - a GL context, which must have been made current once
    
    Returns:
    
    the index after the inserted data, maybe 0 if nothing has be inserted.
  - addDefaultShaderPrecision
```
public final int addDefaultShaderPrecision(GL2ES2 gl,
                                           int pos)
```
    Adds default precision to source code at given position if required, i.e. es2_default_precision_vp, es2_default_precision_fp, gl3_default_precision_vp_gp, gl3_default_precision_fp or none, depending on the GLSL version being used.
    Note: The shader source to be edit must be created using a mutable StringBuilder.
    
    Parameters:
    
    gl - a GL context, which must have been made current once
    
    pos - position within this mutable shader source.
    
    Returns:
    
    the index after the inserted data, maybe 0 if nothing has be inserted.
  - requiresDefaultPrecision
```
public static final boolean requiresDefaultPrecision(GL2ES2 gl)
```
    Returns true, if GLSL version requires default precision, i.e. ES2 or GLSL [1.30 .. 1.50[.
  - requiresGL3DefaultPrecision
```
public static final boolean requiresGL3DefaultPrecision(GL2ES2 gl)
```
    Returns true, if GL3 GLSL version requires default precision, i.e. GLSL [1.30 .. 1.50[.
  - defaultShaderCustomization
```
public final int defaultShaderCustomization(GL2ES2 gl,
                                            boolean preludeVersion,
                                            boolean addDefaultPrecision)
```
    Default customization of this shader source code.
    Note: The shader source to be edit must be created using a mutable StringBuilder.
    
    Parameters:
    
    gl - a GL context, which must have been made current once
    
    preludeVersion - if true GLContext.getGLSLVersionString() is preluded, otherwise not.
    
    addDefaultPrecision - if true default precision source code line(s) are added, i.e. es2_default_precision_vp, es2_default_precision_fp, gl3_default_precision_vp_gp, gl3_default_precision_fp or none, depending on the GLSL version being used.
    
    Returns:
    
    the index after the inserted data, maybe 0 if nothing has be inserted.

    addGLSLVersion(GL2ES2), addDefaultShaderPrecision(GL2ES2, int)
  - defaultShaderCustomization
```
public final int defaultShaderCustomization(GL2ES2 gl,
                                            boolean preludeVersion,
                                            String esDefaultPrecision)
```
    Default customization of this shader source code.
    Note: The shader source to be edit must be created using a mutable StringBuilder.
    
    Parameters:
    
    gl - a GL context, which must have been made current once
    
    preludeVersion - if true GLContext.getGLSLVersionString() is preluded, otherwise not.
    
    esDefaultPrecision - optional default precision source code line(s) preluded if not null and if GLBase.isGLES(). You may use es2_default_precision_fp for fragment shader and es2_default_precision_vp for vertex shader.
    
    Returns:
    
    the index after the inserted data, maybe 0 if nothing has be inserted.
