Method GL.glIsEnabled()

Method glIsEnabled

int GL.glIsEnabled(int cap)

Description

GL.glIsEnabled returns GL_TRUE if cap is an enabled capability and returns GL_FALSE otherwise. Initially all capabilities except GL_DITHER are disabled; GL_DITHER is initially enabled.

The following capabilities are accepted for cap:

Parameter cap

Specifies a symbolic constant indicating a GL capability.

Throws

GL_INVALID_ENUM is generated if cap is not an accepted value.

GL_INVALID_OPERATION is generated if GL.glIsEnabled is executed between the execution of GL.glBegin and the corresponding execution of GL.glEnd.
