Method Detail

nonNull

public static GraphQLNonNull nonNull(GraphQLType wrappedType)

A factory method for creating non null types so that when used with static imports allows more readable code such as .type(nonNull(GraphQLString))

Parameters:

wrappedType - the type to wrap as being non null

Returns:

a GraphQLNonNull of that wrapped type

getWrappedType

public GraphQLType getWrappedType()

Specified by:

getWrappedType in interface GraphQLModifiedType

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getName

public java.lang.String getName()

Specified by:

getName in interface GraphQLType

Returns:

the name of the type which MUST fit within the regular expression [_A-Za-z][_0-9A-Za-z]*

accept

public TraversalControl accept(TraverserContext<GraphQLType> context,
                               GraphQLTypeVisitor visitor)

Description copied from interface: GraphQLType

Double-dispatch entry point. It allows to travers a given non-trivial graphQL type and move from root to nested or enclosed types. This implements similar pattern as Node, see accept(...) for more details about the pattern.

Specified by:

accept in interface GraphQLType

Parameters:

context - TraverserContext bound to this graphQL type object

visitor - Visitor instance that performs actual processing on the types(s)

Returns:

Result of Visitor's operation. Note! Visitor's operation might return special results to control traversal process.

getChildren

public java.util.List<GraphQLType> getChildren()

Specified by:

getChildren in interface GraphQLType

Returns:

returns all types directly associated with this node
