Method Detail

getName

public String getName()

Description copied from interface: SymbolStriper

Returns a string representation of this striper. This string representation should be parseable into this striper via SymbolStriperFactory.

Specified by:

getName in interface SymbolStriper

toString

public String toString()

Description copied from interface: SymbolStriper

Returns a string representation of this striper.

Specified by:

toString in interface SymbolStriper

Overrides:

toString in class Object

SymbolStriper.getName()

getScheme

public DataScheme getScheme()

Description copied from interface: SymbolStriper

Returns scheme that this striper works for. Returns null if this striper works for any scheme.

Specified by:

getScheme in interface SymbolStriper

getStripeCount

public int getStripeCount()

Description copied from interface: SymbolStriper

Returns the positive number of stripes that this striper splits into.

Specified by:

getStripeCount in interface SymbolStriper

Returns:

number of stripes (must be positive)

getStripeIndex

public int getStripeIndex(int cipher,
                          String symbol)

Description copied from interface: SymbolStriper

Returns the index of the stripe that the given cipher-symbol pair falls into.

Note that wildcard symbol should not be submitted to this method, since it should be accepted by all stripes therefore making stripes intersecting each other.

Specified by:

getStripeIndex in interface SymbolStriper

Parameters:

cipher - symbol cipher

symbol - symbol string

Returns:

stripe index

See Also:

QDFilter.accept(QDContract, DataRecord, int, String)

getStripeIndex

public int getStripeIndex(String symbol)

Description copied from interface: SymbolStriper

Returns the index of the stripe that the given symbol falls into.

Specified by:

getStripeIndex in interface SymbolStriper

Parameters:

symbol - symbol string (not-null)

Returns:

stripe index

See Also:

SymbolStriper.getStripeIndex(int, String)

getStripeIndex

public int getStripeIndex(char[] symbol,
                          int offset,
                          int length)

Description copied from interface: SymbolStriper

Returns the index of the stripe that the given symbol (represented as character array) falls into.

Specified by:

getStripeIndex in interface SymbolStriper

Parameters:

symbol - array that is the source of the symbol

offset - the initial offset

length - the symbol's length

Returns:

stripe index

Returns filter corresponding for the given stripe index.

Specified by:

getStripeFilter in interface SymbolStriper

Parameters:

stripeIndex - stripe index

Returns:

QD filter for the stripe
