Method Detail

newCollector

public static DataFetchingFieldSelectionSet newCollector(ExecutionContext executionContext,
                                                         GraphQLType fieldType,
                                                         java.util.List<Field> fields)

get

public java.util.Map<java.lang.String,java.util.List<Field>> get()

Specified by:

get in interface DataFetchingFieldSelectionSet

Specified by:

get in interface java.util.function.Supplier<java.util.Map<java.lang.String,java.util.List<Field>>>

Returns:

a map of the fields that represent the selection set

getArguments

public java.util.Map<java.lang.String,java.util.Map<java.lang.String,java.lang.Object>> getArguments()

Specified by:

getArguments in interface DataFetchingFieldSelectionSet

Returns:

a map of the arguments for each field in the selection set

getDefinitions

public java.util.Map<java.lang.String,GraphQLFieldDefinition> getDefinitions()

Specified by:

getDefinitions in interface DataFetchingFieldSelectionSet

Returns:

a map of the GraphQLFieldDefinitions for each field in the selection set

contains

public boolean contains(java.lang.String fieldGlobPattern)

Description copied from interface: DataFetchingFieldSelectionSet

This will return true if the field selection set matches a specified "glob" pattern matching ie the glob pattern matching supported by FileSystem.getPathMatcher(java.lang.String). This will allow you to use '*', '**' and '?' as special matching characters such that "invoice/customer*" would match an invoice field with child fields that start with 'customer'.

Specified by:

contains in interface DataFetchingFieldSelectionSet

Parameters:

fieldGlobPattern - the glob pattern to match fields against

Returns:

true if the selection set contains these fields

FileSystem.getPathMatcher(String)

getField

public SelectedField getField(java.lang.String fqFieldName)

Description copied from interface: DataFetchingFieldSelectionSet

This will return a selected field using the fully qualified field name.

Specified by:

getField in interface DataFetchingFieldSelectionSet

Parameters:

fqFieldName - the fully qualified name that is contained in the map from DataFetchingFieldSelectionSet.get()

Returns:

a selected field or null if there is no matching field

getFields

public java.util.List<SelectedField> getFields(java.lang.String fieldGlobPattern)

Description copied from interface: DataFetchingFieldSelectionSet

This will return a list of selected fields that match a specified "glob" pattern matching ie the glob pattern matching supported by FileSystem.getPathMatcher(java.lang.String). This will allow you to use '*', '**' and '?' as special matching characters such that "invoice/customer*" would match an invoice field with child fields that start with 'customer'.

Specified by:

getFields in interface DataFetchingFieldSelectionSet

Parameters:

fieldGlobPattern - the glob pattern to match fields against

Returns:

a list of selected fields or empty list if none match

getFields

public java.util.List<SelectedField> getFields()

Description copied from interface: DataFetchingFieldSelectionSet

This will return all selected fields.

Specified by:

getFields in interface DataFetchingFieldSelectionSet

Returns:

a list of all selected fields or empty list if none match
