Method Detail

output

protected final void output(String s)

getShader

public final String getShader()

getParser

protected final JSLParser getParser()

getHeader

protected String getHeader()

Returns the String that will be included at the top of the resulting shader code. This method is called after the entire program has been scanned, so it provides a way for a subclass to customize the header (for example, to include declarations for "special" variables such as pos1 based on whether they were referenced somewhere in the JSL code). The default implementation returns an empty string, but subclasses may override this to provide different behavior.

getPrecision

protected String getPrecision(Precision p)

getType

protected abstract String getType(Type t)

getQualifier

protected abstract String getQualifier(Qualifier q)

getVar

protected abstract String getVar(String v)

getFuncName

protected abstract String getFuncName(String f)
