Method Detail

isDefined

public boolean isDefined(String symbol)

Checks if a symbol is defined. Note that this does do stem tail resolution and namespace resolution.

Parameters:

symbol -

Returns:

getValue

public Object getValue(String variableName)

GetValue may return null if the variable has not been set.

Parameters:

variableName -

Returns:

getValue

public Object getValue(String variableName,
                       Set<XKey> checkedAliases)

setValue

public void setValue(String variableName,
                     Object value)

setValue

public void setValue(String variableName,
                     Object value,
                     Set<XKey> checkedAliases)

remove

public void remove(String variableName)

gsrNSStemOp

protected Object gsrNSStemOp(StemMultiIndex w,
                             int op,
                             Object value,
                             Set<XKey> checkInstances)

gsr = get, set or remove. This resolves the name of the

Parameters:

w -

op -

value -

Returns:

gsrNSScalarOp
