Interface IExpressionTypeState

All Known Implementing Classes:

PromiseVariableTreeTypeState, PromiseVariableTreeTypeStateWithSubStates, ThreadSafeVariableTreeTypeState, VariableTreeTypeState, VariableTreeTypeStateWithSubStates, VariableTypeState

public interface IExpressionTypeState

Describe state of expression.
Each state corresponding to change type of expression.
Also we can say, that state is a node of graph.

Method Summary

void	addExpressionRelatedTypes(Expression baseExpression, Collection<? extends TypeItem> types)	Adds types to state.
void	addType(TypeItem type)	Add type to state
void	addTypes(VariableTypeState state)	Add type to state from another state
void	addTypes(Collection<? extends TypeItem> types)	Add types to state
Iterable<IExpressionTypeState>	getChildState()	Gets children states for current state
Environments	getEnvironments()	Gets corresponding Environment for current state
IExpressionTypeState	getParentState()	Gets state that was before current state
Iterable<TypeItem>	getTypes()	Gets all types associated with this state
int	getTypesSize()	Gets type's list size

Method Detail

getEnvironments

Environments getEnvironments()

Gets corresponding Environment for current state

Returns:

Environments, never null

getTypes

Iterable<TypeItem> getTypes()

Gets all types associated with this state

Returns:

list of TypeItem

hasTypes

boolean hasTypes()

Checks that state has assosiated types

Returns:

true if there are assosiated types in state, false otherwise

addType

void addType(TypeItem type)

Add type to state

Parameters:

type - adding TypeItem, can't be null

addTypes

void addTypes(Collection<? extends TypeItem> types)

Add types to state

Parameters:

types - adding TypeItems, can't be null

addExpressionRelatedTypes

void addExpressionRelatedTypes(Expression baseExpression,
                               Collection<? extends TypeItem> types)

Adds types to state. Method removes old types related to baseExpression and add new related types

Parameters:

baseExpression - Expression which provides adding types, cannot be null

types - setting TypeItems, cannot be null

addTypes

void addTypes(VariableTypeState state)

Add type to state from another state

Parameters:

state - VariableTypeState for adding types, can't be null

getTypesSize

int getTypesSize()

Gets type's list size

Returns:

count of types in VariableTypeState

getParentState

IExpressionTypeState getParentState()

Gets state that was before current state

Returns:

parent state

setParentState

void setParentState(IExpressionTypeState parentState)

Sets state that was before current state.
Remark that in addChildState(IExpressionTypeState) parent state set automatically

Parameters:

parentState - parent state

getChildState

Iterable<IExpressionTypeState> getChildState()

Gets children states for current state

Returns:

list of IExpressionTypeState

addChildState

void addChildState(IExpressionTypeState childState)

Add new child state.
Remarks that current state will be parent state for childState

Parameters:

childState - new child
