Interface RawPixelsStore

All Superinterfaces:

ServiceInterface, StatefulServiceInterface

All Known Implementing Classes:

RawPixelsBean

public interface RawPixelsStore
extends StatefulServiceInterface

Binary data provider. Initialized with the id of a Pixels instance, this interface can provide various slices, stacks, regions of the 5-dimensional (X-Y planes with multiple Z-sections and Channels over Time). The byte array returned by the getter methods and passed to the setter methods can and will be interpreted according to results of getByteWidth(), isFloat(), and isSigned().

Method Detail

setPixelsId

void setPixelsId(long pixelsId,
                 boolean bypassOriginalFile)

Initializes the stateful service for a given Pixels set.

Parameters:

pixelsId - Pixels set identifier.

bypassOriginalFile - Whether or not to bypass checking for an original file to back the pixel buffer used by this service. If requests are predominantly write-only or involve the population of a brand new pixel buffer using true here is a safe optimization otherwise false is expected.

getPixelsPath

String getPixelsPath()

Returns the current Pixels path.

Returns:

See above.

getPixelsId

long getPixelsId()

Returns the current Pixels set identifier.

Returns:

See above.

prepare

void prepare(Set<Long> pixelsIds)

Prepares the stateful service with a cache of loaded Pixels objects. This method is designed to combat query overhead, where many sets of Pixels are to be read from or written to, by loading all the Pixels sets at once. Multiple calls will result in the existing cache being overwritten.

Parameters:

pixelsIds - Pixels IDs to cache.

getPlaneSize

long getPlaneSize()

Returns the plane size

Returns:

the plane size

getRowSize

int getRowSize()

getStackSize

long getStackSize()

getTimepointSize

long getTimepointSize()

getTotalSize

long getTotalSize()

getRowOffset

getPlaneOffset

long getPlaneOffset(int z,
                    int c,
                    int t)

getStackOffset

long getStackOffset(int c,
                    int t)
