Method Summary

Modifier and Type	Method and Description
boolean	canBeCaptured()
IReducedSymbol	createReducedSymbol()

String	getDisplayName() Returns the Symbol's optional display name.
ISymbolTable	getDynamicSymbolTable()
int	getIndex()
ISymbol	getLightWeightReference() Creates a copy of this symbol without the value so that the empty symbol can be stored.

IType	getType() Returns the Symbol's type.
Object	getValue() Returns the value assigned to this Symbol.
boolean	hasDynamicSymbolTable()
boolean	isLocal()
boolean	isValueBoxed()
boolean	isWritable() Returns true if this symbol is writable.
ICapturedSymbol	makeCapturedSymbol(String strName, ISymbolTable symbolTable, IScope scope)
void	setDefaultValueExpression(IExpression defaultValue)
void	setDynamicSymbolTable(ISymbolTable symTable) Assigns an optional symbol table so that the symbol can get/set its value dynamically e.g., via ThreadLocalSymbolTable.
void	setType(IType type) Sets the Symbol's type.
void	setValue(Object value) Assigns a value to this Symbol.
void	setValueIsBoxed(boolean b) Indicates that this symbol should use a reference rather than storing its value directly.

Method Detail

getName

String getName()

Returns the Symbol's name.

Specified by:

getName in interface IReducedSymbol

getDisplayName

String getDisplayName()

Returns the Symbol's optional display name. If a display name is not assigned, returns the symbol's name.

Specified by:

getDisplayName in interface IReducedSymbol

getType

IType getType()

Returns the Symbol's type.

Specified by:

getType in interface IHasType

Specified by:

getType in interface IReducedSymbol

setType

void setType(IType type)

Sets the Symbol's type.

getValue

Object getValue()

Returns the value assigned to this Symbol.

setValue

void setValue(Object value)

Assigns a value to this Symbol.

getDefaultValueExpression

IExpression getDefaultValueExpression()

The symbol's default value e.g., a default parameter value for a function.

Specified by:

getDefaultValueExpression in interface IReducedSymbol

setDefaultValueExpression

void setDefaultValueExpression(IExpression defaultValue)

setDynamicSymbolTable

void setDynamicSymbolTable(ISymbolTable symTable)

Assigns an optional symbol table so that the symbol can get/set its value dynamically e.g., via ThreadLocalSymbolTable.

hasDynamicSymbolTable

boolean hasDynamicSymbolTable()

getDynamicSymbolTable

ISymbolTable getDynamicSymbolTable()

getLightWeightReference

ISymbol getLightWeightReference()

Creates a copy of this symbol without the value so that the empty symbol can be stored.

isWritable

boolean isWritable()

Returns true if this symbol is writable.

An example of a symbol that is not writable is a readonly Property referenced as a symbol in a Gosu class.

setValueIsBoxed

void setValueIsBoxed(boolean b)

Indicates that this symbol should use a reference rather than storing its value directly.

isValueBoxed

boolean isValueBoxed()

Specified by:

isValueBoxed in interface IReducedSymbol

getIndex

int getIndex()

Specified by:

getIndex in interface IReducedSymbol

canBeCaptured

boolean canBeCaptured()

makeCapturedSymbol

ICapturedSymbol makeCapturedSymbol(String strName,
                                   ISymbolTable symbolTable,
                                   IScope scope)

isLocal

boolean isLocal()

getModifierInfo

IModifierInfo getModifierInfo()

createReducedSymbol

IReducedSymbol createReducedSymbol()
