Class FieldCoordinates

java.lang.Object

graphql.schema.FieldCoordinates

@PublicApi
public class FieldCoordinates
extends java.lang.Object

A field in graphql is uniquely located within a parent type and hence code elements like DataFetcher need to be specified using those coordinates.

Method Detail

getTypeName

public java.lang.String getTypeName()

getFieldName

public java.lang.String getFieldName()

assertValidNames

public void assertValidNames()
                      throws AssertException

Checks the validity of the field coordinate names. The validity checks vary by coordinate type. Standard coordinates validate both the typeName and fieldName, while system coordinates do not have a parent so they only validate the fieldName.

Throws:

AssertException - if the coordinates are NOT valid; otherwise, returns normally.

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

coordinates

public static FieldCoordinates coordinates(GraphQLFieldsContainer parentType,
                                           GraphQLFieldDefinition fieldDefinition)

Creates new field coordinates

Parameters:

parentType - the container of the field

fieldDefinition - the field definition

Returns:

new field coordinates represented by the two parameters

coordinates

public static FieldCoordinates coordinates(java.lang.String parentType,
                                           java.lang.String fieldName)

Creates new field coordinates

Parameters:

parentType - the container of the field

fieldName - the field name

Returns:

new field coordinates represented by the two parameters

systemCoordinates

public static FieldCoordinates systemCoordinates(java.lang.String fieldName)

The exception to the general rule is the system __xxxx Introspection fields which have no parent type and are able to be specified on any type

Parameters:

fieldName - the name of the system field which MUST start with __

Returns:

the coordinates
