Constructor Detail

MathProcessor

public MathProcessor(PovclipseProjectProcessor projectProcessor)

Method Detail

setIniDocument

public void setIniDocument(IniDocument iniDocument)

getConstant

public RValue getConstant(java.lang.String name)

Find this constant.

Parameters:

name - The constant to find

Returns:

null if this name is not a povray constant.

getVersion

public double getVersion()

setVersion

public void setVersion(double newVersion)

versionCheck

public boolean versionCheck(PovClipseToken token,
                            int markerLength,
                            double expectedVersion)

Check if we are least the expectedVersion return true if yes, otherwise mark the token and return false

Parameters:

token - The possibly offending token

markerLength - How long to make the marker (#for is 4, not the length of the #for/#end atom)

expectedVersion - The minimum version to use this token's feature

Returns:
