newUnsharedContextFrom

public JCGLContextType newUnsharedContextFrom(long context,
                                              String name)
                                       throws JCGLException,
                                              JCGLExceptionUnsupported,
                                              JCGLExceptionNonCompliant

Description copied from interface: JCGLImplementationLWJGL3Type

Construct a new context from the given context. The long value is a context value returned from GLFW.glfwCreateWindow(int, int, CharSequence, long, long).

The context is assumed not to be shared with any other context. The implementation trusts that this is the case and has no way to verify otherwise.

Specified by:

newUnsharedContextFrom in interface JCGLImplementationLWJGL3Type

Parameters:

context - An existing context

name - The name assigned to the context, for debugging purposes

Returns:

A new context

Throws:

JCGLException - On errors

JCGLExceptionUnsupported - If the context is of a version that is not supported

JCGLExceptionNonCompliant - If the context violates the OpenGL specification

newSharedContextsFrom

public com.io7m.jfunctional.Pair<JCGLContextType,JCGLContextType> newSharedContextsFrom(long master_context,
                                                                                        String master_name,
                                                                                        long slave_context,
                                                                                        String slave_name)
                                                                                 throws JCGLException,
                                                                                        JCGLExceptionUnsupported,
                                                                                        JCGLExceptionNonCompliant

Description copied from interface: JCGLImplementationLWJGL3Type

Construct a new context from the given context. The long values are context values returned from GLFW.glfwCreateWindow(int, int, CharSequence, long, long).

The pair of contexts are assumed to be shared with each other. The implementation trusts that this is the case and has no way to verify otherwise.

On successfully returning, the master_context context will be current on the current thread.

Specified by:

newSharedContextsFrom in interface JCGLImplementationLWJGL3Type

Parameters:

master_context - An existing context

master_name - The name assigned to the master context, for debugging purposes

slave_context - An existing slave context

slave_name - The name assigned to the slave context, for debugging purposes

Returns:

A new context

Throws:

JCGLException - On errors

JCGLExceptionUnsupported - If the context is of a version that is not supported

JCGLExceptionNonCompliant - If the context violates the OpenGL specification
