Method Detail

analyse

public static ELFAnalyser analyse(java.lang.String filename)
                           throws java.io.IOException

Throws:

java.io.IOException

isELF

public boolean isELF()

Returns:

true if the parsed file was detected to be an ELF file

is64Bit

public boolean is64Bit()

Returns:

true if the parsed file was detected to be for a 64bit architecture and pointers are expected to be 8byte wide

isBigEndian

public boolean isBigEndian()

Returns:

true if the parsed file is detected to be big endian, false if the file is little endian

getFilename

public java.lang.String getFilename()

Returns:

filename of the parsed file

isArmHardFloat

public boolean isArmHardFloat()

isArmEabiAapcsVfp

public boolean isArmEabiAapcsVfp()

Returns:

true if file was detected to specify, that FP parameters/result passing conforms to AAPCS, VFP variant (hardfloat)

isArmHardFloatFlag

public boolean isArmHardFloatFlag()

Returns:

true if file was detected to conform to the hardware floating-point procedure-call standard via ELF flags

isArmSoftFloatFlag

public boolean isArmSoftFloatFlag()

Returns:

true if file was detected to conform to the software floating-point procedure-call standard via ELF flags

isArm

public boolean isArm()

Returns:

true if the parsed file was detected to be build for the arm architecture
