public WorkflowConditionBooleanInterpreter()

Method Details

visitBooleanTerm

public Boolean visitBooleanTerm(WorkflowConditionParser.BooleanTermContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.booleanTerm().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitBooleanTerm in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitBooleanTerm in class WorkflowConditionBaseVisitor<Boolean>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitRelationOperand

public Boolean visitRelationOperand(WorkflowConditionParser.RelationOperandContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.relationOperand().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitRelationOperand in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitRelationOperand in class WorkflowConditionBaseVisitor<Boolean>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitBooleanValue

public Boolean visitBooleanValue(WorkflowConditionParser.BooleanValueContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.booleanValue().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitBooleanValue in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitBooleanValue in class WorkflowConditionBaseVisitor<Boolean>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitAtom

public Boolean visitAtom(WorkflowConditionParser.AtomContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.atom().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitAtom in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitAtom in class WorkflowConditionBaseVisitor<Boolean>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitBooleanExpression

public Boolean visitBooleanExpression(WorkflowConditionParser.BooleanExpressionContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.booleanExpression().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitBooleanExpression in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitBooleanExpression in class WorkflowConditionBaseVisitor<Boolean>

Parameters:

ctx - the parse tree

Returns:

the visitor result

visitRelation

public Boolean visitRelation(WorkflowConditionParser.RelationContext ctx)

Description copied from class: WorkflowConditionBaseVisitor

Visit a parse tree produced by WorkflowConditionParser.relation().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitRelation in interface WorkflowConditionVisitor<Boolean>

Overrides:

visitRelation in class WorkflowConditionBaseVisitor<Boolean>

Parameters:
