Method Detail

getPackedGitOpenFiles

public int getPackedGitOpenFiles()
Returns:
maximum number of streams to open at a time. Open packs count against the process limits. Default is 128.

setPackedGitOpenFiles

public void setPackedGitOpenFiles(int fdLimit)
Parameters:
fdLimit - maximum number of streams to open at a time. Open packs count against the process limits

getPackedGitLimit

public long getPackedGitLimit()
Returns:
maximum number bytes of heap memory to dedicate to caching pack file data. Default is 10 MB.

setPackedGitLimit

public void setPackedGitLimit(long newLimit)
Parameters:
newLimit - maximum number bytes of heap memory to dedicate to caching pack file data.

getPackedGitWindowSize

public int getPackedGitWindowSize()
Returns:
size in bytes of a single window mapped or read in from the pack file. Default is 8 KB.

setPackedGitWindowSize

public void setPackedGitWindowSize(int newSize)
Parameters:
newSize - size in bytes of a single window read in from the pack file.

isPackedGitMMAP

public boolean isPackedGitMMAP()
Returns:
true enables use of Java NIO virtual memory mapping for windows; false reads entire window into a byte[] with standard read calls. Default false.

setPackedGitMMAP

public void setPackedGitMMAP(boolean usemmap)
Parameters:
usemmap - true enables use of Java NIO virtual memory mapping for windows; false reads entire window into a byte[] with standard read calls.

getDeltaBaseCacheLimit

public int getDeltaBaseCacheLimit()
Returns:
maximum number of bytes to cache in DeltaBaseCache for inflated, recently accessed objects, without delta chains. Default 10 MB.

setDeltaBaseCacheLimit

public void setDeltaBaseCacheLimit(int newLimit)
Parameters:
newLimit - maximum number of bytes to cache in DeltaBaseCache for inflated, recently accessed objects, without delta chains.

getStreamFileThreshold

public int getStreamFileThreshold()
Returns:
the size threshold beyond which objects must be streamed.

setStreamFileThreshold

public void setStreamFileThreshold(int newLimit)
Parameters:
newLimit - new byte limit for objects that must be streamed. Objects smaller than this size can be obtained as a contiguous byte array, while objects bigger than this size require using an ObjectStream.

fromConfig

public void fromConfig(Config rc)
Update properties by setting fields from the configuration.

If a property is not defined in the configuration, then it is left unmodified.

Parameters:
rc - configuration to read properties from.
