Method Details

getMaxLength

long getMaxLength()
           throws SQLException

Return the maximum number of bytes this opaque object can hold.

Returns:

the maximum opaque size; return 0 if unbounded.

Throws:

SQLException

isTrustedLibrary

boolean isTrustedLibrary()
                  throws SQLException

Indicates whether the Trusted Library implementing Support functions are specified for the Opaque type. This is the case for internal Opaque Types that are modeled in C.

Returns:

true if the Trusted Library implementing Support functions are specified; false, otherwise.

Throws:

SQLException

isModeledInC

boolean isModeledInC()
              throws SQLException

Indicates whether the Opaque type is modelled in C language.

Returns:

true if the Opaque type is modelled in C language; false, otherwise.

Throws:

SQLException

hasUnboundedSize

boolean hasUnboundedSize()
                  throws SQLException

Indicates whether the Opaque type has unbounded size ().

Returns:

true if the Opaque type hsa unbounded size; false, otherwise.

Throws:

SQLException

hasFixedSize

boolean hasFixedSize()
              throws SQLException

Indicates whether the Opaque type has fixed size.

Returns:

true if the Opaque type has fixed size; false, otherwise.

Throws:

SQLException
