Method Detail

displaySize

public int displaySize()

Overrides:

displaySize in class BinaryType

getJDBCTypeCode

public int getJDBCTypeCode()

Description copied from class: Type

Returns the JDBC type number of type, if it exists, otherwise the HSQLDB / SQL type.

Overrides:

getJDBCTypeCode in class BinaryType

getJDBCClass

public java.lang.Class getJDBCClass()

Overrides:

getJDBCClass in class BinaryType

getJDBCClassName

public java.lang.String getJDBCClassName()

Description copied from class: Type

Returns the JDBC class name of type, if it exists, otherwise the HSQLDB class name.

Overrides:

getJDBCClassName in class BinaryType

getNameString

public java.lang.String getNameString()

Description copied from class: Type

Returns the name of the type

Overrides:

getNameString in class BinaryType

getFullNameString

public java.lang.String getFullNameString()

Description copied from class: Type

Returns the name of the type

Overrides:

getFullNameString in class Type

getDefinition

public java.lang.String getDefinition()

Description copied from class: Type

Returns the full definition of the type, including parameters

Overrides:

getDefinition in class BinaryType

isBinaryType

public boolean isBinaryType()

Overrides:

isBinaryType in class BinaryType

isLobType

public boolean isLobType()

Overrides:

isLobType in class Type

acceptsPrecision

public boolean acceptsPrecision()

Overrides:

acceptsPrecision in class BinaryType

getMaxPrecision

public long getMaxPrecision()

Overrides:

getMaxPrecision in class BinaryType

requiresPrecision

public boolean requiresPrecision()

Overrides:

requiresPrecision in class BinaryType

compare

public int compare(Session session,
                   java.lang.Object a,
                   java.lang.Object b)

Overrides:

compare in class BinaryType

convertToTypeLimits

public java.lang.Object convertToTypeLimits(SessionInterface session,
                                            java.lang.Object a)

                                   Type otherType)

Description copied from class: Type

Explicit casts are handled by this method. SQL standard 6.12 rules for enforcement of size, precision and scale are implemented. For CHARACTER values, it performs truncation in all cases of long strings.

Overrides:

Description copied from class: Type

Same as castToType except for CHARACTER values. Perform string truncation of trailing spaces only. For other long strings, it raises an exception.

Overrides:

convertToType in class BinaryType
