Constructors

CatchClauseImpl({required Token? onKeyword, required TypeAnnotationImpl? exceptionType, required Token? catchKeyword, required Token? leftParenthesis, required CatchClauseParameterImpl? exceptionParameter, required Token? comma, required CatchClauseParameterImpl? stackTraceParameter, required Token? rightParenthesis, required BlockImpl body})
Initialize a newly created catch clause. The onKeyword and exceptionType can be null if the clause will catch all exceptions. The comma and _stackTraceParameter can be null if the stack trace parameter is not defined.

Properties

beginToken → Token
Return the first token included in this node's source range.
no setteroverride
body ↔ BlockImpl
Return the body of the catch block.
getter/setter pairoverride-getter
catchKeyword → Token?
The token representing the 'catch' keyword, or null if there is no 'catch' keyword.
final
childEntities → Iterable<SyntacticEntity>
Return an iterator that can be used to iterate through all the entities (either AST nodes or tokens) that make up the contents of this node, including doc comments but excluding other comments.
no setterinherited
comma → Token?
The comma separating the exception parameter from the stack trace parameter, or null if there is no stack trace parameter.
final
end → int
Return the offset of the character immediately following the last character of this node's source range.
no setterinherited
endToken → Token
Return the last token included in this node's source range.
no setteroverride
exceptionParameter ↔ CatchClauseParameterImpl?
Return the parameter whose value will be the exception that was thrown, or null if there is no 'catch' keyword.
getter/setter pairoverride-getter
exceptionParameter2 → CatchClauseParameterImpl?
Return the parameter whose value will be the exception that was thrown, or null if there is no 'catch' keyword.
no setteroverride
exceptionType ↔ TypeAnnotationImpl?
Return the type of exceptions caught by this catch clause, or null if this catch clause catches every type of exception.
getter/setter pairoverride-getter
hashCode → int
The hash code for this object.
no setterinherited
isSynthetic → bool
Return true if this node is a synthetic node.
no setterinherited
leftParenthesis → Token?
The left parenthesis, or null if there is no 'catch' keyword.
final
length → int
Return the number of characters in the syntactic entity's source range.
no setterinherited
namedChildEntities → Iterable<ChildEntity>
Return properties (tokens and nodes) of this node, with names, in the order in which these entities should normally appear, not necessary in the order they really are (because of recovery).
no setterinherited
offset → int
Return the offset from the beginning of the file to the first character in the syntactic entity.
no setterinherited
onKeyword → Token?
The token representing the 'on' keyword, or null if there is no 'on' keyword.
final
parent → AstNode?
Return this node's parent node, or null if this node is the root of an AST structure.
no setterinherited
rightParenthesis → Token?
The right parenthesis, or null if there is no 'catch' keyword.
final
root → AstNode
Return the node at the root of this node's AST structure.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stackTraceParameter ↔ CatchClauseParameterImpl?
Return the parameter whose value will be the stack trace associated with the exception, or null if there is no stack trace parameter.
getter/setter pairoverride-getter
stackTraceParameter2 → CatchClauseParameterImpl?
Return the parameter whose value will be the stack trace associated with the exception, or null if there is no stack trace parameter.
no setteroverride

Methods

accept<E>(AstVisitor<E> visitor) → E?
Use the given visitor to visit this node.
override
detachFromParent() → void
inherited
findPrevious(Token target) → Token?
Return the token before target or null if it cannot be found.
inherited
getProperty<E>(String name) → E?
Return the value of the property with the given name, or null if this node does not have a property with the given name.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setProperty(String name, Object? value) → void
Set the value of the property with the given name to the given value. If the value is null, the property will effectively be removed.
inherited
thisOrAncestorMatching<E extends AstNode>(bool predicate(AstNode)) → E?
Return either this node or the most immediate ancestor of this node for which the predicate returns true, or null if there is no such node.
inherited
thisOrAncestorOfType<E extends AstNode>() → E?
Return either this node or the most immediate ancestor of this node that has the given type, or null if there is no such node.
inherited
toSource() → String
Return a textual description of this node in a form approximating valid source.
inherited
toString() → String
A string representation of this object.
inherited
visitChildren(AstVisitor visitor) → void
Use the given visitor to visit all of the children of this node.
