value - of

id - of the trace object

Method Details

getArray

public Object getArray()
                throws SQLException

Returns the value as a Java array. This method always returns an Object[].

Specified by:

getArray in interface Array

Returns:

the Object array

Throws:

SQLException

getArray

public Object getArray(Map<String,Class<?>> map)
                throws SQLException

Returns the value as a Java array. This method always returns an Object[].

Specified by:

getArray in interface Array

Parameters:

map - is ignored. Only empty or null maps are supported

Returns:

the Object array

Throws:

SQLException

getArray

public Object getArray(long index,
 int count)
                throws SQLException

Returns the value as a Java array. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count. This method always returns an Object[].

Specified by:

getArray in interface Array

Parameters:

index - the start index of the subset (starting with 1)

count - the maximum number of values

Returns:

the Object array

Throws:

SQLException

getArray

public Object getArray(long index,
 int count,
 Map<String,Class<?>> map)
                throws SQLException

Returns the value as a Java array. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count. This method always returns an Object[].

Specified by:

getArray in interface Array

Parameters:

index - the start index of the subset (starting with 1)

count - the maximum number of values

map - is ignored. Only empty or null maps are supported

Returns:

the Object array

Throws:

SQLException

getBaseType

public int getBaseType()
                throws SQLException

Returns the base type of the array.

Specified by:

getBaseType in interface Array

Returns:

the base type or Types.NULL

Throws:

SQLException

getBaseTypeName

public String getBaseTypeName()
                       throws SQLException

Returns the base type name of the array. This database does support mixed type arrays and therefore there is no base type.

Specified by:

getBaseTypeName in interface Array

Returns:

the base type name or "NULL"

Throws:

SQLException

getResultSet

public ResultSet getResultSet()
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value.

Specified by:

getResultSet in interface Array

Returns:

the result set

Throws:

SQLException

getResultSet

public ResultSet getResultSet(Map<String,Class<?>> map)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value.

Specified by:

getResultSet in interface Array

Parameters:

map - is ignored. Only empty or null maps are supported

Returns:

the result set

Throws:

SQLException

getResultSet

public ResultSet getResultSet(long index,
 int count)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count.

Specified by:

getResultSet in interface Array

Parameters:

index - the start index of the subset (starting with 1)

count - the maximum number of values

Returns:

the result set

Throws:

SQLException

getResultSet

public ResultSet getResultSet(long index,
 int count,
 Map<String,Class<?>> map)
                       throws SQLException

Returns the value as a result set. The first column contains the index (starting with 1) and the second column the value. A subset of the array is returned, starting from the index (1 meaning the first element) and up to the given object count.

Specified by:

getResultSet in interface Array

Parameters:

index - the start index of the subset (starting with 1)

count - the maximum number of values

map - is ignored. Only empty or null maps are supported

Returns:

the result set

Throws:

SQLException

free

public void free()

Release all resources of this object.

Specified by:

free in interface Array

getResultSetImpl

private ResultSet getResultSetImpl(long index,
 int count)

checkClosed

private void checkClosed()

get
