Method Detail

isArrayType

public boolean isArrayType()

Returns:

true if this type is an array

isRootType

public boolean isRootType()

The type system allows for the creation of user defined types (UDTs) which can be based on any existing type. When a type does not extend another type, it is considered to be a base or root type in the type hierarchy.

Returns:

true if this type is a base/root type

isEnumType

public boolean isEnumType()

Returns:

true if this type is an enum type

getName

public String getName()

Returns:

symbolic name of the type

getOid

public int getOid()

Returns:

PostgreSQL OID of this type

getJdbcId

public int getJdbcId()

Returns:

JDBC id of the type as reported by JDBC metadata

getElementType

public PostgresType getElementType()

Returns:

the type of element in arrays or null for primitive types

getParentType

public PostgresType getParentType()

Returns:

the parent postgres type this type is based upon

getRootType

public PostgresType getRootType()

Returns:

the postgres type at the top/root level for this type's hierarchy

getEnumValues

public List<String> getEnumValues()

getDefaultLength

public int getDefaultLength()

Returns:

the default length of the type

getDefaultScale

public int getDefaultScale()

Returns:

the default scale of the type

length

public int length(int modifier)

Parameters:

modifier - - type modifier coming from decoder

Returns:

length of the type based on the modifier

getTypeInfo

public org.postgresql.core.TypeInfo getTypeInfo()

Get the underlying postgres type information object

Returns:

the type information object; may be null

scale

public int scale(int modifier)

Parameters:

modifier - - type modifier coming from decoder

Returns:

scale of the type based on the modifier

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
