Constructor Detail

StandardJarScanFilter

public StandardJarScanFilter()

This is the standard implementation of JarScanFilter. By default, the following filtering rules are used:

• JARs that match neither the skip nor the scan list will be included in scan results.
• JARs that match the skip list but not the scan list will be excluded from scan results.
• JARs that match the scan list will be included from scan results.

The default skip list and default scan list are obtained from the system properties Constants.SKIP_JARS_PROPERTY and Constants.SCAN_JARS_PROPERTY respectively. These default values may be over-ridden for the JarScanType.TLD and JarScanType.PLUGGABILITY scans. The filtering rules may also be modified for these scan types using setDefaultTldScan(boolean) and setDefaultPluggabilityScan(boolean). If set to false, the following filtering rules are used for associated type:

• JARs that match neither the skip nor the scan list will be excluded from scan results.
• JARs that match the scan list but not the skip list will be included in scan results.
• JARs that match the skip list will be excluded from scan results.

Method Detail

getTldSkip

public java.lang.String getTldSkip()

setTldSkip

public void setTldSkip(java.lang.String tldSkip)

getTldScan

public java.lang.String getTldScan()

setTldScan

public void setTldScan(java.lang.String tldScan)

isSkipAll

public boolean isSkipAll()

Specified by:

isSkipAll in interface JarScanFilter

Returns:

true if all of the scans should be skipped which can improve startup performance. The default is false.

isDefaultTldScan

public boolean isDefaultTldScan()

setDefaultTldScan

public void setDefaultTldScan(boolean defaultTldScan)

getPluggabilitySkip

public java.lang.String getPluggabilitySkip()

setPluggabilitySkip

public void setPluggabilitySkip(java.lang.String pluggabilitySkip)

getPluggabilityScan

public java.lang.String getPluggabilityScan()

setPluggabilityScan

public void setPluggabilityScan(java.lang.String pluggabilityScan)

isDefaultPluggabilityScan

public boolean isDefaultPluggabilityScan()

setDefaultPluggabilityScan

public void setDefaultPluggabilityScan(boolean defaultPluggabilityScan)

check

public boolean check(JarScanType jarScanType,
                     java.lang.String jarName)

Specified by:

check in interface JarScanFilter

Parameters:

jarScanType - The type of JAR scan currently being performed

jarName - The name of the JAR file (without any path information) to be checked to see if it should be included in the results or not

Returns:

true if the JAR should be returned in the results, false if it should be excluded
