Method Details

init

private void init()

isTopLevel

public boolean isTopLevel()

Specified by:

isTopLevel in interface DebuggableScript

isFunction

public boolean isFunction()

Description copied from interface: DebuggableScript

Returns true if this is a function, false if it is a script.

Specified by:

isFunction in interface DebuggableScript

getFunctionName

public String getFunctionName()

Description copied from interface: DebuggableScript

Get name of the function described by this script. Return null or an empty string if this script is not a function.

Specified by:

getFunctionName in interface DebuggableScript

getParamCount

public int getParamCount()

Description copied from interface: DebuggableScript

Get number of declared parameters in the function. Return 0 if this script is not a function.

Specified by:

getParamCount in interface DebuggableScript

See Also:

• DebuggableScript.getParamOrVarName(int index)

getParamAndVarCount

public int getParamAndVarCount()

Description copied from interface: DebuggableScript

Get number of declared parameters and local variables. Return number of declared global variables if this script is not a function.

Specified by:

getParamAndVarCount in interface DebuggableScript

See Also:
