Method Detail

getMappingContext

MappingContext<? extends org.springframework.data.relational.core.mapping.RelationalPersistentEntity<?>,? extends org.springframework.data.relational.core.mapping.RelationalPersistentProperty> getMappingContext()

Returns the underlying MappingContext used by the converter.

Specified by:

getMappingContext in interface org.springframework.data.relational.core.conversion.RelationalConverter

Returns:

never null

getConversionService

ConversionService getConversionService()

Returns the underlying ConversionService used by the converter.

Specified by:

getConversionService in interface org.springframework.data.relational.core.conversion.RelationalConverter

Returns:

never null.

getArrayValue

Object getArrayValue(org.springframework.data.relational.core.dialect.ArrayColumns arrayColumns,
                     org.springframework.data.relational.core.mapping.RelationalPersistentProperty property,
                     Object value)

Convert a value into an array representation according to ArrayColumns.

Parameters:

arrayColumns - dialect-specific array handling configuration.

property -

value -

Returns:

getTargetType

Class<?> getTargetType(Class<?> valueType)

Return the target type for a value considering registered converters.

Parameters:

valueType - must not be null.

Returns:

Since:

1.1

isSimpleType

boolean isSimpleType(Class<?> type)

Return whether the type is a simple type. Simple types are database primitives or types with a custom mapping strategy.

Parameters:

type - the type to inspect, must not be null.

Returns:

true if the type is a simple one.

Since:

1.2
