Method Detail

getName

public String getName()

Gets space name to which this configuration applies.

Returns:

Space name.

setName

public void setName(String name)

Sets space name.

Parameters:

name - Space name.

isIndexPrimitiveKey

public boolean isIndexPrimitiveKey()

Gets flag indicating whether indexing SPI should index by key in cases where key is primitive type

Returns:

True if primitive keys should be indexed.

setIndexPrimitiveKey

public void setIndexPrimitiveKey(boolean idxPrimitiveKey)

Sets flag indicating whether indexing SPI should index by key in cases where key is primitive type.

Parameters:

idxPrimitiveKey - True if primitive keys should be indexed.

isIndexPrimitiveValue

public boolean isIndexPrimitiveValue()

Gets flag indicating whether indexing SPI should index by value in cases where value is primitive type

Returns:

True if primitive values should be indexed.

setIndexPrimitiveValue

public void setIndexPrimitiveValue(boolean idxPrimitiveVal)

Sets flag indexing whether indexing SPI should index by value in cases where value is primitive type.

Parameters:

idxPrimitiveVal - True if primitive values should be indexed.

isIndexFixedTyping

public boolean isIndexFixedTyping()

This flag essentially controls whether all values of the same type have identical key type.

If false, SPI will store all keys in BINARY form to make it possible to store the same value type with different key types. If true, key type will be converted to respective SQL type if it is possible, hence, improving performance of queries.

Setting this value to false also means that '_key' column cannot be indexed and cannot participate in query where clauses. The behavior of using '_key' column in where clauses with this flag set to false is undefined.

Returns:

True if SPI should try to convert values to their respective SQL types for better performance.

setIndexFixedTyping

public void setIndexFixedTyping(boolean idxFixedTyping)

This flag essentially controls whether key type is going to be identical for all values of the same type.

If false, SPI will store all keys in BINARY form to make it possible to store the same value type with different key types. If true, key type will be converted to respective SQL type if it is possible, which may provide significant performance boost.

Parameters:

idxFixedTyping - True if SPI should try to convert values to their respective SQL types for better performance.

toString

public String toString()

Overrides:
