Constructor Details

TwoDimensionPrimitiveArrayEncoder

TwoDimensionPrimitiveArrayEncoder(ArrayEncoding.AbstractArrayEncoder<A> support)

Parameters:

support - The instance providing support for the base array type.

Method Details

getDefaultArrayTypeOid

public int getDefaultArrayTypeOid()

The default array type oid supported by this instance.

Specified by:

getDefaultArrayTypeOid in interface ArrayEncoding.ArrayEncoder<A>

Returns:

The default array type oid supported by this instance.

toArrayString

public String toArrayString(char delim,
 A[] array)

Creates String representation of the array.

Specified by:

toArrayString in interface ArrayEncoding.ArrayEncoder<A>

Parameters:

delim - The character to use to delimit between elements.

array - The array to represent as a String.

Returns:

String representation of the array.

appendArray

public void appendArray(StringBuilder sb,
 char delim,
 A[] array)

Append String representation of array to sb.

Specified by:

appendArray in interface ArrayEncoding.ArrayEncoder<A>

Parameters:

sb - The StringBuilder to append to.

delim - The delimiter between elements.

array - The array to represent. Will not be null, but may contain null elements.

supportBinaryRepresentation

public boolean supportBinaryRepresentation(int oid)

Indicates if an array can be encoded in binary form to array oid.

Specified by:

supportBinaryRepresentation in interface ArrayEncoding.ArrayEncoder<A>

Parameters:

oid - The array oid to see check for binary support.

Returns:

Indication of whether ArrayEncoding.ArrayEncoder.toBinaryRepresentation(BaseConnection, Object, int) is supported for oid.

toBinaryRepresentation

public byte[] toBinaryRepresentation(BaseConnection connection,
 A[] array,
 int oid)
                              throws SQLException,
SQLFeatureNotSupportedException

Creates binary representation of the array. 4 bytes - dimension 4 bytes - oid 4 bytes - ? 8*d bytes - dimension length

Specified by:

toBinaryRepresentation in interface ArrayEncoding.ArrayEncoder<A>

Parameters:

connection - The connection the binary representation will be used on. Attributes from the connection might impact how values are translated to binary.

array - The array to binary encode. Must not be null, but may contain null elements.

oid - The array type oid to use. Calls to ArrayEncoding.ArrayEncoder.supportBinaryRepresentation(int) must have returned true.

Returns:

The binary representation of array.

Throws:

SQLFeatureNotSupportedException - If ArrayEncoding.ArrayEncoder.supportBinaryRepresentation(int) is false for oid.

SQLException
