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

assertNonNullWrapping

private void assertNonNullWrapping(GraphQLType wrappedType)

getWrappedType

public GraphQLType getWrappedType()

Specified by:

getWrappedType in interface GraphQLModifiedType

getOriginalWrappedType

public GraphQLType getOriginalWrappedType()

replaceType

void replaceType(GraphQLType type)

isEqualTo

public boolean isEqualTo(java.lang.Object o)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

accept

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

Specified by:

accept in interface GraphQLSchemaElement

getChildren

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

Specified by:

getChildren in interface GraphQLSchemaElement

getChildrenWithTypeReferences

public SchemaElementChildrenContainer getChildrenWithTypeReferences()

Specified by:

getChildrenWithTypeReferences in interface GraphQLSchemaElement

withNewChildren

public GraphQLSchemaElement withNewChildren(SchemaElementChildrenContainer newChildren)

Specified by:

withNewChildren in interface GraphQLSchemaElement

copy

public GraphQLSchemaElement copy()

Description copied from interface: GraphQLSchemaElement

Each GraphQLSchemaElement should make a copy of itself when this is called. The copy should be included its current contents as they currently exist into a new object.

Specified by:

copy in interface GraphQLSchemaElement

Returns:

a copy of this element

equals

public final boolean equals(java.lang.Object o)

No GraphQLSchemaElement implements `equals` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

equals in interface GraphQLSchemaElement

Overrides:

equals in class java.lang.Object

Parameters:

o - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public final int hashCode()

No GraphQLSchemaElement implements `equals/hashCode` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

hashCode in interface GraphQLSchemaElement

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.
